摘要： A polyolefin microporous membrane is capable of achieving a low shutdown temperature while keeping air permeation resistance sufficiently low, and a method produces the polyolefin microporous membrane. The polyolefin microporous membrane has, when a temperature is raised to 230° C. at a temperature rise rate of 10° C./min in differential scanning calorimetry (DSC), a ratio of a melting heat quantity (ΔH

摘要： In an apparatus for manufacturing a microporous plastic film roll by conveying a microporous plastic film by conveying rollers and then winding the microporous plastic film in a roll shape while being brought close to a near roller or being brought into contact with a touch roller, a part of the touch roller to be in contact with the plastic film has a Vickers hardness of 100 to 2,000, and the microporous plastic film is conveyed so that a side of the microporous plastic film opposite the side being in contact with the conveying rollers is in a noncontact state in a range being in contact with the conveying rollers.
